Cannot add a static binding for DHCP server

Hello,

I recently bought HPE MSR2003 for an office router.

I created a DHCP pool and tried to enter static bindings. I used the web browser and the console interface and the result is the same. Both are not accepting a MAC address (00-04-13-31-A9-36). I tried writing it with : instead of - and the result was the same. I cannot execute the command. I also tried other MAC addresses without luck.
